Dynamic Asymmetric Connectedness in Technological Sectors
SSRN Electronic Journal, 2022This paper investigates the asymmetric, time, and frequency-based volatility spillovers in global IT industries. To this end, we introduce a new Wavelet-Time Varying Parameter-VAR (W-TVP-VAR) approach to compute connectedness combined with the asymmetrical connectedness of (Barndorff-Nielsen et al., 2010) and (Baruník et al., 2016, 2017) at different ...

Shape, connectedness and dynamics in neuronal networks
Journal of Neuroscience Methods, 2013The morphology of neurons is directly related to several aspects of the nervous system, including its connectedness, health, development, evolution, dynamics and, ultimately, behavior. Such interplays of the neuronal morphology can be understood within the more general shape-function paradigm.

Geopolitical risk and dynamic connectedness between commodity markets
Energy Economics, 2021In this paper, we use the improved Diebold & Yilmaz method based on TVP-VAR-SV model to analyze dynamic connectedness between energy, precious metal, industrial metal, agriculture and livestock commodity markets. The results show that the energy, industrial metal, and precious metal commodity markets are the information transmitters in commodity ...

The social connectedness of older Europeans: patterns, dynamics and contexts
Journal of European Social Policy, 2009Using longitudinal data from the Survey of Health, Ageing and Retirement in Europe (SHARE), our article shows that the population aged 50 or older is socially connected in several ways. The various dimensions of social connectedness turn out to be complementary rather than substitutive, except for the relationship between informal social relations and

Connectedness arguments in linear dynamics
2011This chapter presents some of the deepest, most beautiful and most useful results from linear dynamics. We obtain Ansari’s theorem that every power of a hypercyclic operator is hypercyclic, the Bourdon–Feldman theorem that every somewhere dense orbit is (everywhere) dense, the Costakis–Peris theorem that every multi-hypercyclic operator is hypercyclic,

Measuring the dynamics of APEC output connectedness
Asian-Pacific Economic Literature, 2018We examine the dynamics of output connectedness of Asian Pacific Economic Cooperation (APEC) economies using time‐varying, region‐specific, generalised connectedness measures. We find that the connectedness of APEC economies with the rest of the world is quite substantial, with the 2008–09 Global Financial Crisis increasing the connectedness measures ...

Connectedness of Julia sets for a quadratic random dynamical system
Ergodic Theory and Dynamical Systems, 2003The paper studies the Julia set of random quadratic groups and in particular, conditions for Julia sets to be totally disconnected. Questions raising and proofs draw on two previous articles by \textit{R. Brück} [Pac. J. Math. 198, 347--372 (2001; Zbl 1045.37030) and J. Lond. Math. Soc., II. Ser. 61, 462--470 (2000; Zbl 1033.37026)]. Let \((c_n)\) be a

On the connectedness of the attainability set for lattice dynamical systems
Journal of Difference Equations and Applications, 2012We prove the Kneser property (i.e. the connectedness and compactness of the attainability set at any time) for lattice dynamical systems in which we do not know whether the property of uniqueness of the Cauchy problem holds or not. Using this property, we can check that the global attractor of the multivalued semiflow generated by such system is ...
